Patent GB-473082-A (GB)
Title: Improvements in the splitting and destructive hydrogenation of carbonaceous substances
IPC: B01J27/22
Filed: 1936-04-28
Abstract: A catalyst or carrier for a catalyst suitable for use in the destructive hydrogenation, cracking, dehydrogenation, refining, hydrofining, or aromatizing hydrogenation of carbonaceous materials is produced by subjecting to distillation, until a coky residue is formed, products free from ash and other insoluble or infusible constituents obtained by extracting solid carbonaceous materials with solvents at elevated temperatures and pressures. The coky residue may be activated by treatment with steam at 800--900 DEG  C., or with acid, or by impregnation with zinc chloride or phosphoric acid which also may be added to the extract prior to distillation.  The carrier may be impregnated with catalysts, e.g. by spraying or mixing it with oxides, sulphides, carbonates, formates, acetates, or oxalates of molybdenum, tungsten chromium, vanadium, zinc, tin, lead iron, cobalt, or nickel.  The activity of the catalyst obtained may be improved by treatment with gases, e.g. hydrogen hydrogen sulphide, carbon disulphide, solvents for the extraction comprise tetrahydronaphthalene, middle oils obtained from tar or by destructive hydrogenation, &c., and the extraction is carried out by treating the solid carbonaceous material with the solvent at 250--500 DEG  C. and under pressures of 50--500 atmos.  The resulting extract is further diluted with solvent, freed from ash by filtration or centrifuging and then heated, e.g. in a rotating drum to 600--100 DEG C. until a coky residue is obtained.  Freely ground bituminous coal, pasted with 1,5 parts by weight of a mixture of tetrahydronaphthalene and cresol, is treated for 1\ba1/2\be hours at 410 DEG  C., and under 100 atmos. pressure.  The product is filtered, free from solvent by distillation, and heated to 900 DEG  C., until a coky residue is formed.  The coke is activated with steam, ground, and impregnated with an aqueous solution of ammonium molybdate.  The catalyst then obtained is used in the conversion of a tar oil by treatment with hydrogen at 470 DEG  C.

Filed: 1931-04-23
Abstract: 381,150. Gyroscopic steering apparatus for torpedoes. WHITEHEAD TORPEDO CO., Ltd. and JONES, A. E., Weymouth, Dorset. April 23, 1931, No. 12112. [Class 9 (ii).] Relates to gyroscopic steering apparatus of the kind in which the gyroscope has three free axes, the flywheel D being pivoted in an inner gimbal ring C trunnioned in an outer or vertical gimbal ring B which is in turn trunnioned in a fixed frame A carried by the torpedo. According to the invention, the chest Fl of the valve F, which is controlled by the outer or vertical gimbal ring B is movable and operated through a reducing gear by the steering piston E<1> so as to effect a " hunting " action to bring the rudder to rest. The rudder is adjusted so that when the gyroscope is in the central position, the rudder has a slight set to counteract any natural tendency of the torpedo to deviate from its course. As shown, the valve F is connected by a link B<2> to a crank B<1> on a trunnion of the gimbal ring B, and the rod E<2> of the piston E<1> is connected by a link E<4> to a lever E<5>, the boss of which screws into a fixed nut F<7> and is attached to the chest F<1> of the valve but can rotate thereon. When the piston moves, the boss of the lever E<5> screws slightly in or out and thus displaces the valve chest F<1> along its axis to follow the valve F. The valve chest has a passage f connected to a source of compressed air, and passages f<1>, f<2> communicating with the ends of the cylinder E one with each end. In a modification, the valve is carried by a trunnion rotatably mounted in the frame of the gyroscope in such a way as to provide for " angle-fire."
